COIN-CONTROLLED DISPENSING APPARATUS.

Application filed May 8, 1922. Serial No. 559,132.

This invention is an improved apparatus whereby an oscillatory handle is adapted to be connected with an oscillatory valve by means of a coin so that the handle will act through the coin to open thevalve and dispense air for filling automobile tires; the handle being reversed manually or automatically first to release the coin and then to close the valve without the intervention of such coin.

The characteristic features of my improved apparatus are set out in the accompanying drawings in illustration thereof.

In the drawings, Fig. 1 is a broken top plan view of a coin controlled apparatus embodying my improvements; Fig. 2 is a sectional view taken on the line 2*-2" of Fig.

1; Fig. 8 is a broken side elevational and irregular sectional view of the same, and Fig. 4 is a sectional view of details in illustration of different positions of the coin and the parts connected thereby in themovement of operating'the valve.

The apparatus, as illustrated in the drawings, is applied to a fluid conduit 1 containing a valve 2 adapted to be operated by a stem 3. A closed box or case 4 is fixed to the conduit 1 (preferably centrally with reference to the valve 2) by the brackets or bearings 5. The box has in the bottom thereof a door 6 adapted to turn on a hinge 7 and to be secured in closed position by the engagement of its hasp 8 with the staple 9 on a side of the box, and the action of a lock 10 fixed to the staple sons to hold the hasp thereon.

A shank 11, preferably consisting of a hollow tube, is fixed on the end of the valve stem 3, and a rod 12 extends into the tube 11, the tube and rod passing through and turning in the respective openings 13 and 14 inthe sides of the box. The rod is provided with a pin or stud 15 which is movable in a circular slot 16 formed in the tube, the rod thus having a limited oscillatory movement relative to the tube and is adapted to turn the same. The tube 11 is provided with the diametrically disposed slots 17 extend ing longitudinally thereof and the rod 12 is provided with the slot 18 adapted to register with the slots in thetube, these slots in their reglsterlng vertical position having in line therewith a slot 19 in the otherwise closed top of the box. 1

A yoke 20 is fixed by a frame 21 within the box beneath the slots 17, 18 and 19, so that when a coin 22 is dropped through the slot 19 and into the registering slots 17 and 18 in line therewith, such coin will fall into.

engagementwith the yoke 20 and be heldco 11 connected by the coin 22 to open the valve 2 and permit the flow of air therethrough, from a source of supply to a tire. 'Upon dispensing the amount of fluid desired, as in drawing sufiicient air to fill a tire tube, the handle 28 is turned clockwise, with the result that the coin 22 is released and drops clear of the yoke 20 to the bottom of the case. Thereafter the stud 15 engages the end of the slot 16,-turns the tube 11 together with the stem 3 and closes the valve 2, the handle 23 engaging the lug 25 0f the top of the box when it reaches the vertical posi tion corresponding to the closed position of the valve.

It will be understood that this closing operation can be effected by elevating the handle 23 from the approximately horizontal to the approximately vertical position manually, or the closure can be effected automati-- cally by means of a coiled spring 26-having one end fixed to an anchor 27 and the other end to the stud'28. Having described my invention, I claim The combination with a rotary valve, of control mechanism therefor comprising relatively revoluble members consisting of a shaft having a rod therein, one of said memhers being connected with said rotary valve and the other ofsaid members having a han-' dle connected therewith, saidv members hav- When turned on ing a coin slot extending diametrically entirely therethrough, a coin support below said slot and relatively to which said members are revoluble to remove a coin from said support, and a pin and slot connection between said revolnble members whereby one of said members is movable by .theiother upon the operation of said handle in one direction and said last named member is movable independently of the other by the movement of the handle in the opposite direction.

In testimony whereof I have hereunto set my name this 24th day of April, 1922.
